Is this normal?

So today is my 19th birthday! I have a great life with great friends and family but one thing is missing. I've never had a boyfriend, I've never kissed a boy or anything. It's not that I'm not interested in boys, I am. I just haven't met the right person yet. Or maybe it was because I was caught up on the same boy for 5 years even though he never liked me. Or maybe I'm just really unattractive. I just see my youth leaving me and all the people my age are in relationships and I wish it was me. I just can't even see myself getting close to someone. I just feel like I'm the only one who's not in a relationship at my age. So my question is, is it normal or acceptable to never have been in a relationship at 19?
